T0 at whom, it may concern:

Be it known that I, EDWARD D. KENDALL, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Portable Soda- WVater Apparatus, or apparatus for charging water with carbon dioxide, usually called carbonic-aeid gas, which improvement is fully set forth in the following specification and ac companying drawings, in which Figure 1 is a perspective view of the appa- Fig. 2 is a sectional view of a part of the apparatus which is to contain the water to be charged with the gas. Fig. 3 is a perspective view of a similar part of the apparatus,whicl1 is to contain the chemicals for generating the gas. Figs. 4, 5, and 6 are separate parts of the apparatus,fu11y described in the specification. Fig. 7 is a pipe for delivering the soda water.

The object of my invention is to provide a safe and simple apparatus for impregnating water with earbonic-acid gas evolved from a mixture of any suitable. chemicals, and it is particularly adapted for use by families and aboard ship.

. In the drawings, Figs. 2 and 3, A and A are vessels made of caoutchouc vulcanized or in the natural condition. In their construction the caoutchouc may be used alone, or it may be first spread on cloth or canvas, in which case the cloth or canvas forms the outside of the vessels. In Fig. 1 these caoutchouc vessels are indicated by A and'A, but are not visible, being surrounded by helices of wire, as will be presently herein described. The vessels A and A differ only in sizeA, which receives the gas-generating chemicals, having, preferably, about half the capacity of A, which contains the water that is to be impregnated with gas. They may be made of comparatively thin material, provided they are surrounded by one wrapping of thick paper or cloth or thin sheet metal, to prevent abrasion and to secure an equal distribution of pressnre on the exterior of the said vessels. Each of the vessels has two necks, B and B small, and C and 0 larger. In the necks B and B are fastened, by cement and wiring, suitable brass connections or couplings. In the neck 0 and C are similarly fastened short brass and A.

caoutchoue to close the tube gas-tight.

D in Fig. 1 is a short piece of rubber tube surrounded by a spiral of wire to prevent bursting, while retaining flexibility. It is terminated at each end by suitable parts of couplings to form connections, as shown, with the smaller necks, B and B, of the vessels A This tube is intended to convey gas from the generator A to the vessel A. It may be of different construction and material. Ordinary lead or block-tin pipe may be used.

In Figs. 1 and 2 a stopcock, L, is shown interposed between one end of the said tube or pipe and the neck B.

At E, Fig. 2, is indicated a tube, preferably of glass or block-tin, connected with the neck B of the vessel A, and reaching nearly to the bottom of the latter. It serves as a continuation of the tube or pipe D, to conduct and deliver the gas.

F and F are closely-wound helices of iron,

steel, or brass wire, (one of which is shown separately in, Fig. 4,) which surround the caoutchouc vessels A and A, to resist lateral J and J are corresponding square plates of metal without the said openings. In Fig. 5, I is a sectional View of one of these plates in a line with the center of two opposite edges. It will be seen that each plate is formed with a circular projection or rim, which is intended to receive and surround one end of a helix. Four strong rods or bolts (one of which is shown in Fig. 6) are screwed into the four corners of each bottom plate, and are fastened into thecorners of each upper plate by screwquantity of water is to be poured into the vessel A through the tube 0, and the required quantity of water to be charged with carbonicacid gas is to be introduced into the vessel A through the tube G. Suitable chemicals, in due proportion, (for example, weighed quantities of bicarbonate of soda and tartaric acid,) are then put into the vessel A through the tube 0, which tube is then to be closed by its screw-cap. The gas forms in A, and, driving before it the contained common air, passes through the tube D and the tube E into the vessel AC After several minutes carbonic acid gas will issue from the tube 0, as indicated by the extinguishment of a lighted match held at the opening, after which this tube also is to be closed by its screw-cap. Occasional agitation of the vessel A facilitates the absorption of the gas. Vhen a sufficient time has elapsed, as determined by experience, to sulfieiently charge the water in A with gas, the stop-cock L is to be closed, the tube D disconnected, and the curved pipe M, Fig. 7 ,screwed on the stop-cock, through which pipe the sodawater may be discharged for consumption.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

In an apparatus for charging .water with carbonic-acid gas, an elastic or expansible vessel for generating the gas, sustained or surrounded by a helical coil of metal as a supporting agent, and a similar expansible vessel for holding water and receiving the gas, also-supported by a surrounding metallic coil or helix, all constructed, arranged, and operating in the manner and for the purposes substantially as set forth and shown.

In testimony whereof I have hereunto set my hand and affixed my seal this 21st day of,

May, 1883.
